Whats is percentage of 25% to 24

Answers

Answer:

96%

hope this helps!!:)

Step-by-step explanation:

Answer:

I think the question is supposed to be What is 25% of 24? Or you are missing a component of the question

Step-by-step explanation:

You could multiply .25 times 24 to get the answer because changing 25% to a number you can use in an equation means adding a decimal place and moving two places to the left.

.25 x 24= 6

6 is 25% of 24

Micah has 15 games. Micah has three more games than kelly. Kelly has K number of games. Move values into the boxes to create an equation to represent this senerio

Answers

Answer:

Equation = K + 3 = 15

K = 12 games

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Micah games = 15

Let, Kelly games = K

As Micah has three more games than Kelly, then

K + 3 = 15

This equation shows the scenario.

We can find the number of games Kelly has by using this equation,

K+3 = 15

K = 15 - 3

K = 12

Hence, Kelly has 12 games.

Martin ordered a pizza with a 12-inch diameter. Ricky ordered a pizza with a 16-inch diameter. What is the approximate difference in area of the two pizzas in

square inches?

OA. 4

OB. 16

O C. 112

O D. 352

Answers

Answer:

88 in²

Step-by-step explanation:

The shape of a pizza = Circular

Area of a circle = πr²

For Martin

Martin ordered a pizza with a 12-inch diameter.

Radius = Diameter/2 = 12 inch/2 = 6 inch

Area of Martin's pizza = π × 6²

= 113.09733553 in²

≈ 113.1 in²

For Ricky

Ricky ordered a pizza with a 16-inch diameter.

Radius = Diameter/2 = 16 inch/2 = 8 inch

Area of Martin's pizza = π × 8²

= 201.06192983in²

= 201.1in²

The approximate difference in area of the two pizzas in square inches is calculated as:

201.1 in² - 113.1 in²

= 88 in²

Ebony is x years old.
Her brother is 4 years older.
Her Mum is 3 times her age.

Write an expression for the age of:
Her mum
Her brother

Answers

Answer:

Ebony's brother is x + 4 years old.

Ebony's mum is 3x years old.

Explanation:

Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.

Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.
